Q. (37/100)

[tex] \\ [/tex]
1.) 2,4 + 8% - ½ = ...

2.) 100% - 10% = ...​

2,4 + 8% - 1/2

=> 2,4 + 0,192 - 2

=> 2,592 - 2

=> 0,592

100% - 10%

=> 1 - 0,1

=> 0,9

Jawaban:

[tex]1) \: 2.4 + 8\% - \frac{1}{2} \\ \\ = \frac{ 24}{10} + \frac{8}{100} - \frac{1}{2} \\ \\ = \frac{24 \times 10}{10 \times 10} + \frac{8}{100} - \frac{1 \times 50}{2 \times 50} \\ \\ = \frac{240}{100} + \frac{8}{100} - \frac{50}{100} \\ \\ = \frac{240 + 8 - 50}{100} \\ \\ = \frac{198}{100} \\ \\ = 1 \frac{98}{100} \\ \\ = 1.98[/tex]

[tex]2)100\% - 10\% \\ \\ = \frac{100}{100} - \frac{10}{100} \\ \\ = \frac{100 - 10}{100} \\ \\ = \frac{90}{100} \\ \\ = 0.9[/tex]
